A73 locks again right after i unlock it, as if unlock fails/crashes.

Latest software update

I noticed this happens occasionally, not always. But whenever it does, it is super annoying. 

When i unlock it with fingerprint, it sort of lags after the unlock, as if something crashed, and locks the phone again, so i need to unlock the phone once more. After it's fine.

Has anyone found a fix to this?

I love this phone, but this one thing is pretty annoying when it happens

That's not good at all. 😒

My suggestion is to clear the phone's System Partition Cache Files Section to see I that helps.
How to > Clear Cache Files from the phone's System Partition Section > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too.
If that fails to help can you put the phone into Safe Mode to see if that helps.
How to > Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
A final resort would be a back up and Factory Reset.
You can send feedback and error reports via your Samsung Members app.
A Samsung Service Centre can certainly take a look at your phone to assess it too.
If I can be of any further help then please don't hesitate. Take care. 😎

I have the same problem, did you manage to fix it??

[Christopher Ellis]

Same issue for my A73 it started to happen after the 5.1 UI update

Still no fix

[veryonline]

same thing happens on my galaxy A23, i think it might just be a recent bug because all the posts I find about this happening have been from March onwards

[Christopher Ellis]

Yes this started happening after I installed the 5.1 update

[R3aps73]

Strange, since the update, it has not happened on my fone

I have the same problem with my A53, specially when the phone is being charged. Did you manage to fix it?

[Christopher Ellis]

Hi Kaveh

The problem seemed to be fixed after I downloaded one of the security updates

So check if you have a software update and that should help

Hi Christopher,

My phone is updated. But the problem still exists!!
